Abstract: A controller reduces a rotational speed of a Rankine cycle from a predetermined normal rotational speed during an operation of a compressor in a predetermined state when the controller determines that a predicted refrigerant flow quantity, which is predicted by assuming that the compressor is operated in a sole operation of the Rankine cycle at the predetermined normal rotational speed of the Rankine cycle, exceeds a predetermined flow quantity. The predetermined state is a state that satisfies a predetermined condition, which relates to the sole operation of the Rankine cycle.

Abstract: Prevention of the incapability of operation due to crystallization in the absorption solution. When the temperature difference (&Dgr;T) between the temperature of the concentrated absorption solution Tr detected by the temperature sensor (22) and the temperature of crystallization Tc for the concentrated absorption solution at a specified concentration detected by the concentration sensor (21) comes within a prescribed figure, the opening of the heat control valve (20) is decreased by a specified figure, 20% for example. When the concentration of the concentrated absorption solution, which is measured by the concentration sensor (21), exceeds a prescribed figure, 65% for example, the heat supplied to the high temperature regenerator (1) is reduced by decreasing the opening of the heat control valve (20) regardless of the above temperature difference (&Dgr;T).

Abstract: A system for cooling electronic equipment, especially modular electronic units mounted in racks, each having a casing with an air inlet, an air outlet and a fan for cooling the contents of the unit. The system uses a chiller unit, between adjacent racks for returning cooled air to ambient, each of which can be a piping array connected to a supply of chilled water. A baffle backing the piping array improves heat exchange and provides a more uniform transfer of heat to each array, thereby enabling optimum temperature differences to be achieved across each rack. A slidable framework supports the piping array and defines an air space on the cooled air side of the array. An auxiliary piping array extends rearwardly of racks so as to communicate with rear air spaces behind the racks and thereby cool heated air flowing in the rear air spaces.

Abstract: Refrigerant vapor generated in a high temperature regenerator is condensed in a condenser, and the refrigerant vapor is changed to refrigerant liquid. Then it is conducted to a first evaporator. The refrigerant vapor evaporated in the first evaporator is absorbed in a solution in a first absorber. The refrigerant liquid conducted from the condenser without vaporizing in the first evaporator is introduced to a second evaporator, and it evaporates in the second evaporator. The refrigerant vapor in the second evaporator is absorbed in the solution in a second absorber. The first and the second evaporator and the first and the second absorber are made of a unitary chamber. The first evaporator is juxtaposed to the second absorber with a heat transfer member. The concentration of the refrigerant in the second evaporator is controlled by a refrigerant liquid controller that controls a flow rate of the refrigerant liquid flowing from the first evaporator at the predetermined value.

Abstract: An air conditioner including an air intake vent, an air blow-off vent for blowing off air which has been heat-exchanged, air-flow direction changing blades which are disposed at the air blow-off vent and serves to change the air-flow (blow-off air) direction, an opening portion through the outside air is supplied from the outside into a room, a closing member (damper) for selectively closing the opening portion, and an open/close operation member which is disposed in a gap between the air-flow direction changing blades and allows the closing member to selectively open or close the opening portion. When the outside air is supplied through the opening portion into the room, a finger is inserted into the gap to move the open/close operation member in a direction along the gap, whereby an outside air work can be simply performed without detaching the front panel from the air conditioner.

Abstract: A transport refrigeration system including a compressor, an evaporator, a condenser, an air mover assembly for the evaporator and condenser comprising fans and/or blowers, and a prime mover for the compressor having first and second selectable speeds. The speed of the air mover assembly is mechanically interlocked with the speed of the prime mover via a pulley driven speed changer, to eliminate the possibility of overspeeding of the air mover assembly. The speed changer changes the speed of the prime mover by a mechanical movement which cannot be made without tension in the pulley belts automatically changing the pulley ratio of the speed changer, to maintain a substantially constant speed for the air mover assembly, notwithstanding a change in prime mover speed.

Abstract: The present invention is directed to a method and apparatus for heat generation or heat exchange in which a primary medium emits heat while passing through an evaporator in which there is a heat-transfer medium which thereby evaporates or boils and thereby increases the pressure of the heat-transfer medium. Once the pressure has increased, it is transferred to a condensor where a secondary medium is heated from the condensation of the heat-transfer medium. The method and device according to the present invention increase the efficiency, particularly when the primary medium is at a low temperature, by intensifying the heat at least in a portion of the evaporator.
